Description

本発明は、電子装置に関する。   The present invention relates to an electronic device.

従来、モータの駆動制御に係る電子装置が知られている。例えば特許文献１では、コントローラは２枚の基板を有している。また、コネクタは、２枚の基板の間に設けられ、コネクタと基板とを接続する端子は、２枚の基板の間から基板に挿入されている。   Conventionally, electronic devices related to motor drive control are known. For example, in Patent Document 1, the controller has two substrates. Further, the connector is provided between the two substrates, and a terminal for connecting the connector and the substrate is inserted into the substrate from between the two substrates.

特開２０１２−１０５７６号公報JP 2012-10576 A

特許文献１のように、コネクタが２枚の基板の間に設けられ、例えばコネクタの端子と基板とをはんだ等により接続する場合、それぞれの基板の外側からはんだ付けを行い、端子の先端側から接続状態を確認可能である。
ところで、例えば２枚の基板の間ではなく、一方の基板側にコネクタが設けられる場合、コネクタ端子と一方の基板との接続箇所が他方の基板等により遮蔽されて、接続状態を端子の先端側から確認できない虞がある。
本発明は、上述の課題に鑑みてなされたものであり、その目的は、コネクタ端子と基板との接続状態をコネクタ側から確認可能な電子装置を提供することにある。 As in Patent Document 1, a connector is provided between two substrates. For example, when connecting a connector terminal and a substrate by soldering or the like, soldering is performed from the outside of each substrate, and from the tip end side of the terminal. The connection status can be confirmed.
By the way, for example, when a connector is provided on one board side instead of between two boards, the connection portion between the connector terminal and one board is shielded by the other board, and the connection state is changed to the tip side of the terminal. There is a possibility that it cannot be confirmed.
The present invention has been made in view of the above-described problems, and an object thereof is to provide an electronic device capable of confirming a connection state between a connector terminal and a substrate from the connector side.

本発明の電子装置は、基板と、コネクタ部と、コネクタ端子と、を備える。
基板は、基板保持部材に保持される。
コネクタ部は、基板を挟んで基板保持部材と反対側に設けられ、周壁部の少なくとも一部が基板の外縁よりも内側となるように形成される。
コネクタ端子は、基板の外縁よりも内側の周壁部から突出して形成され、折曲部にて基板側に折り曲げられて基板と接続される。 The electronic device of the present invention includes a substrate, a connector portion, and a connector terminal.
The substrate is held by the substrate holding member.
The connector portion is provided on the opposite side of the substrate holding member with the substrate interposed therebetween, and is formed so that at least a part of the peripheral wall portion is located inside the outer edge of the substrate.
The connector terminal is formed so as to protrude from the peripheral wall portion inside the outer edge of the substrate, and is bent to the substrate side at the bent portion and connected to the substrate.

基板のコネクタ部側から見たとき、コネクタ端子の折曲部よりも周壁部側である突出部と、基板のスルーホールに挿入される挿入部とは、ずれて形成される。
挿入部と突出部とをずらして形成することで、基板のコネクタ部側から見たとき、基板とコネクタ端子との接続箇所が突出部に隠されない。これにより、コネクタ端子と基板との接続状態を、基板のコネクタ部側から見て確認することができるので、接続の信頼性が向上する。 When viewed from the connector portion side of the substrate, the protruding portion that is on the peripheral wall portion side with respect to the bent portion of the connector terminal and the insertion portion that is inserted into the through hole of the substrate are formed so as to be shifted.
By forming the insertion portion and the protruding portion so as to be shifted, the connecting portion between the substrate and the connector terminal is not hidden by the protruding portion when viewed from the connector portion side of the substrate. Thereby, since the connection state of a connector terminal and a board | substrate can be confirmed seeing from the connector part side of a board | substrate, the reliability of a connection improves.

以下、本発明による電子装置を図面に基づいて説明する。以下、複数の実施形態において、実質的に同一の構成には同一の符号を付して説明を省略する。
（第１実施形態）
本発明の第１実施形態による電子装置を図１〜図５に基づいて説明する。
図１〜図３に示すように、本実施形態の電子装置２０は、駆動装置１に適用される。駆動装置１は、例えば電動パワーステアリング装置に適用される。
駆動装置１は、モータ１０と、電子装置２０と、を備える。
モータ１０は、図示しないステータ、ロータ、および、ロータと一体に回転するシャフト等を備え、モータケース１１に収容される。モータケース１１は、軸方向において、出力端と反対側の端部が開口し、この開口側から電子装置２０の一部が挿入される。
本実施形態では、モータ１０を軸方向に投影したモータ領域において、モータ１０の径方向を単に「径方向」といい、モータ１０の軸方向（図１における紙面上下方向）を単に「軸方向」という。 Hereinafter, an electronic device according to the present invention will be described with reference to the drawings. Hereinafter, in a plurality of embodiments, the same numerals are given to the substantially same composition, and explanation is omitted.
(First embodiment)
An electronic device according to a first embodiment of the present invention will be described with reference to FIGS.
As shown in FIGS. 1 to 3, the electronic device 20 of this embodiment is applied to the driving device 1. The drive device 1 is applied to, for example, an electric power steering device.
The drive device 1 includes a motor 10 and an electronic device 20.
The motor 10 includes a stator (not shown), a rotor, a shaft that rotates integrally with the rotor, and the like, and is accommodated in a motor case 11. The motor case 11 is open at the end opposite to the output end in the axial direction, and a part of the electronic device 20 is inserted from the opening side.
In the present embodiment, in the motor area in which the motor 10 is projected in the axial direction, the radial direction of the motor 10 is simply referred to as “radial direction”, and the axial direction of the motor 10 (the vertical direction in FIG. 1) is simply “axial direction”. That's it.

電子装置２０は、コントロールユニット３０、および、コネクタ部５０を備える。
コントロールユニット３０は、制御基板３１、パワー基板３２、および、保持部材４０等を備える。
制御基板３１は、保持部材４０のモータ１０側にねじ等で固定される。制御基板３１には、マイコンやプリドライバ等の制御系の電子部品が実装される。本実施形態では、図１中に矢印Ｙで示すように、電子装置２０の制御基板３１側がモータケース１１に挿入される。 The electronic device 20 includes a control unit 30 and a connector unit 50.
The control unit 30 includes a control board 31, a power board 32, a holding member 40, and the like.
The control board 31 is fixed to the motor 10 side of the holding member 40 with screws or the like. Control system electronic components such as a microcomputer and a pre-driver are mounted on the control board 31. In the present embodiment, as indicated by an arrow Y in FIG. 1, the control board 31 side of the electronic device 20 is inserted into the motor case 11.

パワー基板３２は、保持部材４０のモータ１０と反対側にねじ等で固定される。パワー基板３２には、図示しないコンデンサ等の比較的通電量の大きいパワー系の電子部品が実装される。パワー基板３２には、電源端子６１が挿入されるスルーホール３２１、および、グランド端子６２が挿入されるスルーホール３２２が形成される（図２参照）。本実施形態では、パワー基板３２のコネクタ部５０側の面を第１面３２５、保持部材４０側の面を第２面３２６とする。
本実施形態では、パワー基板３２が「基板」に対応する。
制御基板３１とパワー基板３２との間には、モータ巻線への通電を切り替えるスイッチング素子を有する図示しないパワーモジュールが設けられる。パワーモジュールは、通電により生じる熱を保持部材４０に放熱可能に設けられる。 The power board 32 is fixed to the opposite side of the holding member 40 from the motor 10 with screws or the like. On the power board 32, a power electronic component having a relatively large energization amount such as a capacitor (not shown) is mounted. A through hole 321 into which the power supply terminal 61 is inserted and a through hole 322 into which the ground terminal 62 is inserted are formed in the power board 32 (see FIG. 2). In the present embodiment, the surface on the connector portion 50 side of the power board 32 is a first surface 325 and the surface on the holding member 40 side is a second surface 326.
In the present embodiment, the power board 32 corresponds to a “board”.
Between the control board 31 and the power board 32, a power module (not shown) having a switching element for switching energization to the motor winding is provided. The power module is provided so that heat generated by energization can be radiated to the holding member 40.

保持部材４０は、アルミ等の熱伝導性のよい素材で形成され、制御基板３１、パワー基板３２、および、コネクタ部５０を保持する。保持部材４０には、パワー基板３２側に開口する図示しない収容室が形成され、収容室には、パワー基板３２の保持部材４０側の面に実装されるコンデンサ等の大型部品が収容される。   The holding member 40 is formed of a material having good thermal conductivity such as aluminum, and holds the control board 31, the power board 32, and the connector unit 50. The holding member 40 is formed with a storage chamber (not shown) that opens to the power board 32 side, and a large component such as a capacitor mounted on the surface of the power board 32 on the holding member 40 side is stored in the storage chamber.

コネクタ部５０は、基部５１、脚部５２、および、配線接続部５５等を有し、コントロールユニット３０のモータ１０と反対側に設けられる。換言すると、コネクタ部５０は、複数（本実施形態では２枚）の基板３１、３２の間ではなく、パワー基板３２のモータ１０と反対側に配置される。コネクタ部５０は、全体がモータ１０を軸方向に投影した領域であるモータ領域内に収まるように形成される。これにより、駆動装置１の径方向における体格を小型化できる。   The connector part 50 includes a base part 51, leg parts 52, a wiring connection part 55, and the like, and is provided on the opposite side of the control unit 30 from the motor 10. In other words, the connector unit 50 is arranged not on the side of the motor 10 on the power board 32 but on the side of the power board 32, not between a plurality (two in this embodiment) of the boards 31 and 32. The connector portion 50 is formed so as to be entirely within a motor region that is a region in which the motor 10 is projected in the axial direction. Thereby, the physique in the radial direction of the drive device 1 can be reduced in size.

基部５１は、モータ１０の外径よりも小さい略円板状に形成される。図２に示すように、電子装置２０をコネクタ部５０側から軸方向に見たとき、基部５１の周壁部５１１の一部は、パワー基板３２の外縁３２０よりも内側に形成される。
脚部５２は、基部５１のモータ１０側であって、径方向外側に突出して形成され、ねじ等により保持部材４０に固定される。コネクタ部５０が保持部材４０に固定された状態において、基部５１とパワー基板３２とは、軸方向に離間して配置される。 The base 51 is formed in a substantially disk shape that is smaller than the outer diameter of the motor 10. As shown in FIG. 2, when the electronic device 20 is viewed in the axial direction from the connector part 50 side, a part of the peripheral wall part 511 of the base part 51 is formed inside the outer edge 320 of the power board 32.
The leg portion 52 is formed on the motor 10 side of the base portion 51 so as to protrude radially outward, and is fixed to the holding member 40 with a screw or the like. In a state in which the connector part 50 is fixed to the holding member 40, the base part 51 and the power board 32 are arranged apart from each other in the axial direction.

配線接続部５５は、基部５１の略中央にて、モータ１０と反対側に突出して形成される。配線接続部５５は、モータ１０と反対側の端部側に開口し、電源、ＣＡＮ(Contoroller Area NetWork)、各種センサ等との接続に用いられる配線部材等を軸方向端部側から接続可能に形成される。配線接続部５５の開口方向は、軸方向側に限らず、例えば径方向外側を向いていてもよい。
また、コネクタ部５０は、図示しない制御端子により、制御基板３１と接続される。 The wiring connection portion 55 is formed to protrude to the opposite side of the motor 10 at the approximate center of the base portion 51. The wiring connection part 55 opens to the end side opposite to the motor 10 so that a wiring member used for connection to a power source, a CAN (Contoroller Area Network), various sensors, etc. can be connected from the axial end side. It is formed. The opening direction of the wiring connection portion 55 is not limited to the axial direction side, and may be, for example, radially outward.
Moreover, the connector part 50 is connected with the control board 31 by the control terminal which is not shown in figure.

図１〜図５に示すように、周壁部５１１のパワー基板３２の外縁３２０よりも内側に形成される箇所からは、電源端子６１およびグランド端子６２が径方向外側に突出して形成される。電源端子６１は、コネクタ部５０側からパワー基板３２側へ電流が流れ、グランド端子６２は、パワー基板３２側からコネクタ部５０側へ電流が流れる。本実施形態では、電源端子６１とグランド端子６２とは、中心線Ｃに対して線対称に形成される。   As shown in FIGS. 1 to 5, a power supply terminal 61 and a ground terminal 62 are formed so as to protrude outward in the radial direction from a portion formed inside the outer edge 320 of the power board 32 of the peripheral wall portion 511. In the power supply terminal 61, a current flows from the connector part 50 side to the power board 32 side, and in the ground terminal 62, a current flows from the power board 32 side to the connector part 50 side. In the present embodiment, the power supply terminal 61 and the ground terminal 62 are formed symmetrically with respect to the center line C.

電源端子６１は、折曲部６１１にてパワー基板３２側に折り曲げられる。電源端子６１は、先端部６１７側がパワー基板３２のスルーホール３２１に挿入され、はんだ等によりパワー基板３２と電気的に接続される。本実施形態では、電源端子６１は、幅方向の長さよりも厚み方向の長さの方が大きい平板状に形成されるので、スルーホール３２１は、長円形状に形成される。   The power terminal 61 is bent toward the power board 32 at the bent portion 611. The power supply terminal 61 is inserted into the through hole 321 of the power board 32 at the tip 617 side, and is electrically connected to the power board 32 by solder or the like. In the present embodiment, since the power supply terminal 61 is formed in a flat plate shape having a length in the thickness direction larger than a length in the width direction, the through hole 321 is formed in an oval shape.

図４に示すように、電源端子６１において、折曲部６１１よりも周壁部５１１側を突出部６１２、折曲部６１１からパワー基板３２側に略垂直に延びる部分を中間部６１３とする。また、中間部６１３から幅方向にずれて形成され、先端部６１７に至る部分を挿入部６１５とする。
突出部６１２は、周壁部５１１からパワー基板３２に略平行に突出する。 As shown in FIG. 4, in the power supply terminal 61, the peripheral wall portion 511 side of the bent portion 611 is a protruding portion 612, and the portion extending substantially perpendicularly from the bent portion 611 to the power board 32 side is an intermediate portion 613. Further, a portion that is formed to be shifted in the width direction from the intermediate portion 613 and reaches the distal end portion 617 is referred to as an insertion portion 615.
The protruding portion 612 protrudes from the peripheral wall portion 511 substantially in parallel to the power board 32.

挿入部６１５は、中間部６１３の先端側にて幅方向に突出するとともに、中間部６１３の先端側の端部６１４よりも、先端部６１７が折曲部６１１と反対側に延びて形成される。本実施形態では、挿入部６１５は、中間部６１３よりもグランド端子６２側に形成される。挿入部６１５は、パワー基板３２に略垂直に形成され、先端部６１７側がスルーホール３２１に挿入される。
先端部６１７には、厚み方向に貫通する切欠部６１８が形成される。 The insertion portion 615 protrudes in the width direction on the distal end side of the intermediate portion 613, and the distal end portion 617 extends to the opposite side of the bent portion 611 from the end portion 614 on the distal end side of the intermediate portion 613. . In the present embodiment, the insertion portion 615 is formed closer to the ground terminal 62 than the intermediate portion 613. The insertion portion 615 is formed substantially perpendicular to the power substrate 32, and the distal end portion 617 side is inserted into the through hole 321.
A cutout portion 618 that penetrates in the thickness direction is formed in the distal end portion 617.

グランド端子６２は、電源端子６１と同様、基部５１の周壁部５１１から径方向外側に突出し、折曲部６２１にてパワー基板３２側に折り曲げられる。グランド端子６２は、先端部６２７側がパワー基板３２のスルーホール３２２に挿入され、はんだ等によりパワー基板３２と電気的に接続される。本実施形態では、グランド端子６２は、幅方向の長さが厚み方向の長さより大きい平板状に形成されるので、スルーホール３２２は、長円形状に形成される。   Similarly to the power supply terminal 61, the ground terminal 62 protrudes radially outward from the peripheral wall portion 511 of the base portion 51, and is bent toward the power board 32 at the bent portion 621. The ground terminal 62 is inserted into the through hole 322 of the power board 32 at the tip 627 side, and is electrically connected to the power board 32 by solder or the like. In the present embodiment, the ground terminal 62 is formed in a flat plate shape whose length in the width direction is larger than the length in the thickness direction, and thus the through hole 322 is formed in an oval shape.

本実施形態では、グランド端子６２において、折曲部６２１よりも周壁部５１１側を突出部６２２、折曲部６２１からパワー基板３２側に略垂直に延びる部分を中間部６２３とする。また、中間部６２３から幅方向にずれて形成され、先端部６２７に至る部分を挿入部６２５とする。
突出部６２２は、周壁部５１１からパワー基板３２に略平行に突出する。 In the present embodiment, in the ground terminal 62, the peripheral wall portion 511 side of the bent portion 621 is a protruding portion 622, and a portion extending substantially perpendicularly from the bent portion 621 to the power board 32 side is an intermediate portion 623. In addition, a portion that is formed to be shifted from the intermediate portion 623 in the width direction and reaches the distal end portion 627 is referred to as an insertion portion 625.
The protruding portion 622 protrudes substantially parallel to the power board 32 from the peripheral wall portion 511.

挿入部６２５は、中間部６２３の先端側にて幅方向に突出するとともに、中間部６２３の先端側の端部６２４よりも、先端部６１７が折曲部６１１と反対側に延びて形成される。本実施形態では、挿入部６２５は、中間部６２３よりも電源端子６１側に形成される。挿入部６２５は、パワー基板３２に略垂直に形成され、先端部６２７側がスルーホール３２２に挿入される。
先端部６２７には、厚み方向に貫通する切欠部６２８が形成される。
本実施形態では、電源端子６１およびグランド端子６２が「コネクタ端子」に対応する。 The insertion portion 625 protrudes in the width direction on the distal end side of the intermediate portion 623, and the distal end portion 617 extends to the opposite side of the bent portion 611 from the end portion 624 on the distal end side of the intermediate portion 623. . In the present embodiment, the insertion portion 625 is formed closer to the power supply terminal 61 than the intermediate portion 623. The insertion portion 625 is formed substantially perpendicular to the power board 32, and the distal end portion 627 side is inserted into the through hole 322.
A cutout portion 628 that penetrates in the thickness direction is formed in the distal end portion 627.
In the present embodiment, the power supply terminal 61 and the ground terminal 62 correspond to “connector terminals”.

図１および図３に示すように、パワー基板３２の第２面３２６側には、遮蔽部材としての制御基板３１が設けられている。そのため、スルーホール３２１、３２２は、制御基板３１に覆われた状態となり、制御基板３１側から見えず、制御基板３１側から治具を用いたはんだ付けができない。そのため、本実施形態では、径方向外側に開口する作業空間４９をスルーホール３２１、３２２の第２面３２６側に形成し、作業空間４９の径方向外側から治具等を挿入して端子６１、６２とパワー基板３２とをはんだ等により接続可能である。
なお、図３中では、説明のため、スルーホール３２１、３２２の位置を２点鎖線で記載した。 As shown in FIGS. 1 and 3, a control board 31 as a shielding member is provided on the second surface 326 side of the power board 32. Therefore, the through holes 321 and 322 are covered with the control board 31 and cannot be seen from the control board 31 side, and soldering using a jig cannot be performed from the control board 31 side. Therefore, in this embodiment, the working space 49 that opens radially outward is formed on the second surface 326 side of the through holes 321, 322, and a jig or the like is inserted from the radially outer side of the working space 49 to connect the terminal 61, 62 and the power board 32 can be connected by solder or the like.
In FIG. 3, the positions of the through holes 321 and 322 are indicated by two-dot chain lines for explanation.

また、保持部材４０に制御基板３１が組み付けられた状態において、制御基板３１側から見て、第２面３２６側におけるパワー基板３２と端子６１、６２との接続状態を確認することができない。ここで、仮に、折曲部６１１から真っ直ぐに延びた位置にて電源端子６１とパワー基板３２とが接続される場合、第１面３２５側から見たとき、電源端子６１とパワー基板３２との接続箇所と突出部６１２とが重複するため、第１面３２５側からも接続状態を確認することができない。グランド端子６２についても同様である。   Further, in the state where the control board 31 is assembled to the holding member 40, it is impossible to confirm the connection state between the power board 32 and the terminals 61 and 62 on the second surface 326 side when viewed from the control board 31 side. Here, if the power supply terminal 61 and the power board 32 are connected at a position extending straight from the bent portion 611, when viewed from the first surface 325 side, the power supply terminal 61 and the power board 32 Since the connection location and the protruding portion 612 overlap, the connection state cannot be confirmed from the first surface 325 side. The same applies to the ground terminal 62.

そこで本実施形態では、図２に示すように、電源端子６１において、コネクタ部５０側から軸方向に見て、挿入部６１５と突出部６１２とが重複しないように、挿入部６１５が、スルーホール３２１の長手方向に突出部６１２とずらして形成される。
これにより、電源端子６１とパワー基板３２との接続状態（特に長手方向における接続状態）を、第１面３２５側から確認することができる。 Therefore, in the present embodiment, as illustrated in FIG. 2, in the power supply terminal 61, the insertion portion 615 has a through hole so that the insertion portion 615 and the protrusion 612 do not overlap when viewed in the axial direction from the connector portion 50 side. It is formed so as to be shifted from the protrusion 612 in the longitudinal direction of 321.
Thereby, the connection state (especially the connection state in a longitudinal direction) of the power supply terminal 61 and the power board 32 can be confirmed from the 1st surface 325 side.

同様に、グランド端子６２において、コネクタ部５０側から軸方向に見て、挿入部６２５と突出部６２２とが重複しないように、挿入部６２５が、スルーホール３２２の長手方向に突出部６２２とずらして形成される。
これにより、グランド端子６２とパワー基板３２との接続状態（特に長手方向における接続状態）を、第１面３２５側から確認することができる。 Similarly, in the ground terminal 62, the insertion portion 625 is shifted from the projection portion 622 in the longitudinal direction of the through hole 322 so that the insertion portion 625 and the projection portion 622 do not overlap when viewed in the axial direction from the connector portion 50 side. Formed.
Thereby, the connection state (especially connection state in the longitudinal direction) between the ground terminal 62 and the power board 32 can be confirmed from the first surface 325 side.

また、端子６１、６２の先端部６１７、６２７には、厚み方向に貫通する切欠部６１８、６２８が形成されている。これにより、径方向外側から端子６１、６２とパワー基板３２とをはんだにより接続するとき、端子６１、６２の内側まで、確実にはんだを行き渡らせることができる。また、例えば、先端が３つに分岐した治具を用いれば、端子６１、６２とパワー基板３２との接続に要する作業工数を低減することができる。   Further, notches 618 and 628 penetrating in the thickness direction are formed at the end portions 617 and 627 of the terminals 61 and 62, respectively. Thereby, when connecting the terminals 61 and 62 and the power substrate 32 from outside in the radial direction by solder, the solder can be reliably distributed to the inside of the terminals 61 and 62. Further, for example, if a jig whose tip is branched into three is used, the number of work steps required for connecting the terminals 61 and 62 and the power board 32 can be reduced.

本実施形態では、電源端子６１およびグランド端子６２は、挿入部６１５、６２５が互いに近接する方向に、中間部６１３、６２３から突出して形成される。すなわち、中間部６１３、６２３間の距離をｄ１１、挿入部６１５、６２５間の距離をｄ１２とすると、ｄ１１＞ｄ１２である。また、中間部６１３、６２３の長さをＬ１１、挿入部６１５、６２５の長さをＬ１２とすると、Ｌ１１＞Ｌ１２である。
なお、挿入部６１５、６２５の長さは、コネクタ部５０側の端部から、パワー基板３２までの長さとする。後述の実施形態についても同様とする。 In the present embodiment, the power supply terminal 61 and the ground terminal 62 are formed to protrude from the intermediate portions 613 and 623 in the direction in which the insertion portions 615 and 625 are close to each other. That is, if the distance between the intermediate parts 613 and 623 is d11 and the distance between the insertion parts 615 and 625 is d12, d11> d12. Further, when the length of the intermediate portions 613 and 623 is L11 and the length of the insertion portions 615 and 625 is L12, L11> L12.
The lengths of the insertion portions 615 and 625 are the lengths from the end portion on the connector portion 50 side to the power board 32. The same applies to later-described embodiments.

ここで、例えば同一形状の２つの端子を同じ向きで横並びに配置した場合、中間部間の距離ｄ１１と挿入部間の距離ｄ１２とが同じになる。この場合、挿入部が、自身の突出部および隣接する端子の突出部と重複しないようにするためには、中間部および挿入部を端子幅よりも近接させて配置することができない。
本実施形態では、挿入部６１５、６２５を互いに近接する方向に突出して形成することで、挿入部６１５、６２５を可及的近接させることができる。本実施形態では、電源端子６１には、コネクタ部５０側からパワー基板３２側に電流が流れ、グランド端子６２には、パワー基板３２側からコネクタ部５０側に電流が流れる。すなわち、本実施形態では、電源端子６１とグランド端子６２とで、流れる電流の大きさが同じであって向きが反対であるので、挿入部６１５、６２５を可及的近接させることで磁気回路が小さくなり、磁束漏れを低減することができる。 Here, for example, when two terminals having the same shape are arranged side by side in the same direction, the distance d11 between the intermediate portions and the distance d12 between the insertion portions are the same. In this case, the intermediate portion and the insertion portion cannot be disposed closer to the terminal width in order to prevent the insertion portion from overlapping with the protrusion portion of the own terminal and the adjacent terminal.
In the present embodiment, the insertion portions 615 and 625 can be made as close as possible by forming the insertion portions 615 and 625 so as to protrude in directions close to each other. In the present embodiment, a current flows from the connector part 50 side to the power board 32 side in the power supply terminal 61, and a current flows from the power board 32 side to the connector part 50 side in the ground terminal 62. In other words, in this embodiment, the power terminal 61 and the ground terminal 62 have the same magnitude of flowing current and opposite directions, so that the magnetic circuit can be formed by bringing the insertion portions 615 and 625 as close as possible. The magnetic flux leakage can be reduced.

以上詳述したように、電子装置２０は、パワー基板３２と、コネクタ部５０と、電源端子６１およびグランド端子６２と、を備える。
パワー基板３２は、保持部材４０に保持される。
コネクタ部５０は、パワー基板３２を挟んで保持部材４０と反対側に設けられ、周壁部５１１の少なくとも一部がパワー基板３２の外縁３２０よりも内側となるように形成される。 As described above in detail, the electronic device 20 includes the power board 32, the connector unit 50, the power supply terminal 61 and the ground terminal 62.
The power board 32 is held by the holding member 40.
The connector part 50 is provided on the opposite side of the holding member 40 with the power board 32 interposed therebetween, and is formed such that at least a part of the peripheral wall part 511 is inside the outer edge 320 of the power board 32.

電源端子６１は、パワー基板３２の外縁３２０よりも内側の周壁部５１１から突出して形成され、折曲部６１１にてパワー基板３２側に折り曲げられて、パワー基板３２と接続される。同様に、グランド端子６２は、パワー基板３２の外縁３２０よりも内側の周壁部５１１から突出して形成され、折曲部６２１にてパワー基板３２側に折り曲げられてパワー基板３２と接続される。   The power terminal 61 is formed to protrude from the peripheral wall portion 511 on the inner side of the outer edge 320 of the power substrate 32, is bent toward the power substrate 32 at the bent portion 611, and is connected to the power substrate 32. Similarly, the ground terminal 62 is formed so as to protrude from the peripheral wall portion 511 inside the outer edge 320 of the power substrate 32, and is bent to the power substrate 32 side at the bent portion 621 to be connected to the power substrate 32.

本実施形態では、パワー基板３２のコネクタ部５０側から見たとき、電源端子６１の折曲部６１１よりも周壁部５１１側である突出部６１２と、パワー基板３２のスルーホール３２１に挿入される挿入部６１５とは、ずれて形成される。
また、パワー基板３２のコネクタ部５０側から見たとき、グランド端子６２の折曲部６２１よりも周壁部５１１側である突出部６２２と、パワー基板３２のスルーホール３２２に挿入される挿入部６１５とは、ずれて形成される。 In the present embodiment, when viewed from the connector part 50 side of the power board 32, the power supply terminal 61 is inserted into the protruding part 612 on the peripheral wall part 511 side relative to the bent part 611 of the power supply terminal 61 and the through hole 321 of the power board 32. The insertion portion 615 is formed so as to be shifted.
Further, when viewed from the connector part 50 side of the power board 32, the protruding part 622 that is closer to the peripheral wall part 511 than the bent part 621 of the ground terminal 62 and the insertion part 615 that is inserted into the through hole 322 of the power board 32. Are formed out of alignment.

挿入部６１５、６２５と突出部６１２、６２２とをずらして形成することで、パワー基板３２のコネクタ部５０側から見たとき、端子６１、６２とパワー基板３２との接続箇所が突出部６１２、６２２に隠されない。これにより、端子６１、６２とパワー基板３２との接続状態を、パワー基板３２のコネクタ部５０側から見て確認することができるので、接続の信頼性が向上する。
また、電源端子６１は、中間部６１３と挿入部６１５とがずれて形成されているので、折曲部６１１からパワー基板３２に真っ直ぐに延びるストレート形状に形成される場合と比較し、パワー基板３２と電源端子６１との接続箇所にかかる冷熱や振動等による応力を緩和することができる。 By forming the insertion portions 615 and 625 and the protruding portions 612 and 622 so as to be shifted, when viewed from the connector portion 50 side of the power board 32, the connecting portion between the terminals 61 and 62 and the power board 32 is the protruding portion 612. 622 is not hidden. Thereby, since the connection state of the terminals 61 and 62 and the power board 32 can be confirmed when viewed from the connector portion 50 side of the power board 32, the connection reliability is improved.
Further, since the power supply terminal 61 is formed so that the intermediate portion 613 and the insertion portion 615 are shifted, the power substrate 32 is compared with a case where it is formed in a straight shape extending straight from the bent portion 611 to the power substrate 32. It is possible to relieve stress due to cooling, vibration, or the like applied to the connection point between the power supply terminal 61 and the power supply terminal 61.

また、パワー基板３２のコネクタ部５０と反対側には、スルーホール３２１、３２２を遮蔽する制御基板３１が設けられる。パワー基板３２と制御基板３１との間には、端子６１、６２とパワー基板３２との接続に用いる治具を挿入可能な作業空間４９が形成される。   A control board 31 that shields the through holes 321 and 322 is provided on the opposite side of the power board 32 from the connector portion 50. Between the power board 32 and the control board 31, a work space 49 into which a jig used for connecting the terminals 61 and 62 and the power board 32 can be inserted is formed.

本実施形態では、保持部材４０のパワー基板３２が設けられる側と反対側から見たとき、制御基板３１に遮蔽されて端子６１、６２とパワー基板３２との接続箇所を確認することができないが、コネクタ部５０側から接続状態を確認することができる。また、作業空間４９が形成されているので、例えば径方向外側から治具を挿入し、端子６１、６２とパワー基板３２とを適切に接続することができる。   In the present embodiment, when viewed from the side of the holding member 40 opposite to the side on which the power board 32 is provided, the connection part between the terminals 61 and 62 and the power board 32 cannot be confirmed due to being shielded by the control board 31. The connection state can be confirmed from the connector unit 50 side. In addition, since the work space 49 is formed, for example, a jig can be inserted from the outside in the radial direction, and the terminals 61 and 62 and the power board 32 can be appropriately connected.

挿入部６１５、６２５には、切欠部６１８、６２８が形成される。これにより、例えば径方向外側から治具を挿入してはんだ付けする場合において、端子６１、６２の内側まではんだを行き渡らせることができ、端子６１、６２の内側についても確実に接続することができる。   Cutout portions 618 and 628 are formed in the insertion portions 615 and 625. Thereby, for example, when soldering is performed by inserting a jig from the outside in the radial direction, the solder can be spread to the inside of the terminals 61 and 62, and the inside of the terminals 61 and 62 can also be reliably connected. .

挿入部６１５、６２５は、扁平形状に形成され、突出部６１２、６２２と挿入部６１５、６２５とは、コネクタ部５０側から見た挿入部６１５、６２５の長手方向にずれて形成される。これにより、端子６１、６２とパワー基板３２との接続箇所の長手側の接続状態をコネクタ部５０側から確認することができる。   The insertion portions 615 and 625 are formed in a flat shape, and the protruding portions 612 and 622 and the insertion portions 615 and 625 are formed so as to be shifted in the longitudinal direction of the insertion portions 615 and 625 as viewed from the connector portion 50 side. Thereby, the connection state of the longitudinal side of the connection location of the terminals 61 and 62 and the power board 32 can be confirmed from the connector part 50 side.

本実施形態では、電源端子６１およびグランド端子６２の折曲部６１１、６２１からパワー基板３２側に延びて形成される部分を中間部６１３、６２３とすると、隣り合う２つの端子６１、６２の挿入部６１５、６２５は、互いに近接する方向に、中間部６１３、６２３から突出して形成される。これにより、２つの端子６１、６２に流れる電流の向きが反対向きである場合、磁束漏れを低減することができる。   In the present embodiment, if the portions extending from the bent portions 611 and 621 of the power supply terminal 61 and the ground terminal 62 to the power substrate 32 side are the intermediate portions 613 and 623, the two adjacent terminals 61 and 62 are inserted. The parts 615 and 625 are formed so as to protrude from the intermediate parts 613 and 623 in a direction in which they are close to each other. Thereby, when the direction of the current flowing through the two terminals 61 and 62 is opposite, magnetic flux leakage can be reduced.

（第２実施形態）
本発明の第２実施形態を図６に示す。
本実施形態は、電源端子６３およびグランド端子６４の形状が異なっているので、この点を中心に説明する。図６においては、パワー基板３２、コネクタ部５０の基部５１、電源端子６３、および、グランド端子６４を模式的に示し、他の構成の記載は省略した。図７も同様である。 (Second Embodiment)
A second embodiment of the present invention is shown in FIG.
In the present embodiment, since the shapes of the power terminal 63 and the ground terminal 64 are different, this point will be mainly described. In FIG. 6, the power board 32, the base 51 of the connector unit 50, the power supply terminal 63, and the ground terminal 64 are schematically shown, and descriptions of other configurations are omitted. The same applies to FIG.

電源端子６３は、図示しない突出部、折曲部６３１、中間部６３３、および、挿入部６３５から構成される。本実施形態では、挿入部６３５がグランド端子６４から離間する方向に突出する点を除き、上記実施形態の電源端子６１と略同様である。
グランド端子６４は、図示しない突出部、折曲部６４１、中間部６４３、および、挿入部６４５から構成される。本実施形態では、挿入部６４５が電源端子６３から離間する方向に突出する点を除き、上記実施形態のグランド端子６２と略同様である。 The power terminal 63 includes a projecting portion (not shown), a bent portion 631, an intermediate portion 633, and an insertion portion 635. This embodiment is substantially the same as the power supply terminal 61 of the above embodiment except that the insertion portion 635 protrudes in a direction away from the ground terminal 64.
The ground terminal 64 includes a projecting portion (not shown), a bent portion 641, an intermediate portion 643, and an insertion portion 645. This embodiment is substantially the same as the ground terminal 62 of the above embodiment except that the insertion portion 645 protrudes in a direction away from the power supply terminal 63.

本実施形態では、中間部６３３、６４３間の距離ｄ２１は、挿入部６３５、６４５間の距離ｄ２２より短い。また、中間部６３３、６４３の長さＬ２１は、挿入部６３５、６４５の長さＬ２２よりも長い。すなわち、Ｌ２１＞Ｌ２２である。
本実施形態では、グランド端子６４には、電源端子６３と同じ大きさであって、かつ、方向が反対向きの電流が流れる。そのため、挿入部６３５、６４５よりも近接している中間部６３３、６４３の長さＬ２１を、挿入部６３５、６４５の長さＬ２２よりも大きくすることにより、通電により生じる磁気回路を小さくすることができるので、磁束漏れを低減することができる。 In the present embodiment, the distance d21 between the intermediate portions 633 and 643 is shorter than the distance d22 between the insertion portions 635 and 645. Further, the length L21 of the intermediate portions 633 and 643 is longer than the length L22 of the insertion portions 635 and 645. That is, L21> L22.
In the present embodiment, a current having the same size as that of the power supply terminal 63 and an opposite direction flows through the ground terminal 64. Therefore, by making the length L21 of the intermediate portions 633 and 643 closer to the insertion portions 635 and 645 larger than the length L22 of the insertion portions 635 and 645, the magnetic circuit generated by energization can be reduced. As a result, magnetic flux leakage can be reduced.

本実施形態では、挿入部６３５、６４５を互いに離間する方向に突出して形成することで、中間部６３３、６４３を可及的近接させることができる。これにより、上記実施形態と同様、磁束漏れを低減することができる。また、中間部６３３、６４３の方が、挿入部６３５、６４５よりも近接しているため、中間部６３３、６４３を可及的長くする方が磁束漏れ低減効果は大きいため、Ｌ２１＞Ｌ２２とすることが望ましい。なお、Ｌ２１＞Ｌ２２でなくても磁束漏れ低減効果は期待できるので、Ｌ２１＝Ｌ２２であってもよいし、Ｌ２１＜Ｌ２２であってもよい。   In the present embodiment, the intermediate portions 633 and 643 can be made as close as possible by forming the insertion portions 635 and 645 so as to protrude in directions away from each other. Thereby, like the said embodiment, magnetic flux leakage can be reduced. Further, since the intermediate portions 633 and 643 are closer than the insertion portions 635 and 645, the effect of reducing the magnetic flux leakage is greater when the intermediate portions 633 and 643 are made as long as possible. Therefore, L21> L22. It is desirable. Note that even if L21> L22 is not satisfied, the effect of reducing magnetic flux leakage can be expected, so L21 = L22 may be satisfied, or L21 <L22 may be satisfied.

本実施形態では、端子６３、６４の折曲部６３１、６４１からパワー基板３２側に延びて形成される部分を中間部６３３、６４３とすると、隣り合う２つの端子である端子６３、６４の挿入部６３５、６４５は、互いに離間する方向に、中間部６３３、６４３から突出して形成される。これにより、２つの端子６１、６２に流れる電流の向きが反対向きである場合、磁束漏れを低減することができる。   In the present embodiment, if the intermediate portions 633 and 643 are portions formed by extending the bent portions 631 and 641 of the terminals 63 and 64 to the power board 32 side, the terminals 63 and 64 that are adjacent two terminals are inserted. The parts 635 and 645 are formed to protrude from the intermediate parts 633 and 643 in a direction away from each other. Thereby, when the direction of the current flowing through the two terminals 61 and 62 is opposite, magnetic flux leakage can be reduced.

また、中間部６３３、６４３は、挿入部６３５、６４５よりも長い。これにより、近接する中間部６３３、６４３を可及的に長くすることにより、磁束漏れをより低減することができる。
また、上記実施形態と同様の効果を奏する。
本実施形態では、電源端子６３およびグランド端子６４が「コネクタ端子」に対応する。 Further, the intermediate portions 633 and 643 are longer than the insertion portions 635 and 645. Thereby, magnetic flux leakage can be further reduced by making the adjacent intermediate portions 633 and 643 as long as possible.
In addition, the same effects as those of the above embodiment can be obtained.
In the present embodiment, the power supply terminal 63 and the ground terminal 64 correspond to “connector terminals”.

（第３実施形態）
本発明の第３実施形態を図７に示す。
本実施形態は、電源端子６５およびグランド端子６６の形状が異なっているので、この点を中心に説明する。 (Third embodiment)
A third embodiment of the present invention is shown in FIG.
In the present embodiment, since the shapes of the power terminal 65 and the ground terminal 66 are different, this point will be mainly described.

電源端子６５は、図示しない突出部、折曲部６５１、中間部６５３、および、挿入部６５５から構成される。本実施形態では、第１実施形態と同様、挿入部６５５がグランド端子６６側に突出して形成される。
グランド端子６６は、図示しない突出部、折曲部６６１、中間部６６３、および、挿入部６６５から構成される。本実施形態では、第１実施形態と同様、挿入部６６５が電源端子６５側に突出して形成される。 The power terminal 65 includes a projecting portion (not shown), a bent portion 651, an intermediate portion 653, and an insertion portion 655. In the present embodiment, as in the first embodiment, the insertion portion 655 is formed to project toward the ground terminal 66 side.
The ground terminal 66 includes a projecting portion (not shown), a bent portion 661, an intermediate portion 663, and an insertion portion 665. In the present embodiment, as in the first embodiment, the insertion portion 665 is formed to protrude toward the power supply terminal 65.

本実施形態では、挿入部６５５、６６５間の距離ｄ３２は、中間部６５３、６６３間の距離ｄ３１よりも短い。また、挿入部６５５、６６５の長さＬ３２は、中間部６５３、６６３の長さＬ３１よりも長い。すなわち、Ｌ３１＜Ｌ３２である。
本実施形態では、グランド端子６６には、電源端子６５と同じ大きさであって、かつ、方向が反対向きの電流が流れる。そのため、中間部６５３、６６３よりも近接している挿入部６５５、６６５の長さＬ３２を、中間部６５３、６６３の長さＬ３１よりも大きくすることにより、通電により生じる磁気回路を小さくすることができるので、磁束漏れを低減することができる。 In the present embodiment, the distance d32 between the insertion portions 655 and 665 is shorter than the distance d31 between the intermediate portions 653 and 663. Further, the length L32 of the insertion portions 655 and 665 is longer than the length L31 of the intermediate portions 653 and 663. That is, L31 <L32.
In the present embodiment, a current having the same size as the power supply terminal 65 and the opposite direction flows through the ground terminal 66. Therefore, by making the length L32 of the insertion portions 655 and 665 closer to the intermediate portions 653 and 663 longer than the length L31 of the intermediate portions 653 and 663, the magnetic circuit generated by energization can be reduced. As a result, magnetic flux leakage can be reduced.

本実施形態では、挿入部６５５、６６５の方が、中間部６５３、６６３よりも近接しているため、挿入部６５５、６６５を可及的長くする方が磁束漏れ低減効果は大きいがＬ３１＜Ｌ３２とすることが望ましい。なお、必ずしもＬ３１＜Ｌ３２でなくても磁束漏れ低減効果は期待できるので、Ｌ３１＝Ｌ３２であってもよいし、Ｌ３１＞Ｌ３２であってもよい。   In this embodiment, since the insertion portions 655 and 665 are closer to each other than the intermediate portions 653 and 663, the magnetic flux leakage reduction effect is greater when the insertion portions 655 and 665 are made as long as possible, but L31 <L32 Is desirable. Note that the effect of reducing magnetic flux leakage can be expected even if L31 <L32 is not necessarily satisfied, so L31 = L32 may be satisfied or L31> L32 may be satisfied.

本実施形態では、挿入部６５５、６６５は、中間部６５３、６６３より長い。
これにより、２つの端子６５、６６に流れる電流の向きが反対である場合、近接する挿入部６５５、６６５を可及的に長くすることにより、磁束漏れをより低減することができる。
また、上記実施形態と同様の効果を奏する。
本実施形態では、電源端子６５およびグランド端子６６が「コネクタ端子」に対応する。 In the present embodiment, the insertion portions 655 and 665 are longer than the intermediate portions 653 and 663.
Thereby, when the directions of the currents flowing through the two terminals 65 and 66 are opposite to each other, magnetic flux leakage can be further reduced by making the adjacent insertion portions 655 and 665 as long as possible.
In addition, the same effects as those of the above embodiment can be obtained.
In the present embodiment, the power supply terminal 65 and the ground terminal 66 correspond to “connector terminals”.

（他の実施形態）
（ア）コネクタ端子
上記実施形態では、コネクタ端子は、電源端子およびグランド端子である。他の実施形態では、コネクタ端子は、電源端子およびグランド端子以外の端子であってもよい。また、端子数は２に限らず、いくつであってもよい。
上記実施形態では、コネクタ端子の先端に切欠部が形成される。他の実施形態では、切欠部は、はんだ等をコネクタ端子の内側まで供給可能であれば、個数、形状、形成箇所等は、上記実施形態に限らない。また、切欠部を形成しなくてもよい。 (Other embodiments)
(A) Connector terminal In the said embodiment, a connector terminal is a power supply terminal and a ground terminal. In other embodiments, the connector terminal may be a terminal other than the power supply terminal and the ground terminal. Further, the number of terminals is not limited to two and may be any number.
In the above embodiment, the notch is formed at the tip of the connector terminal. In other embodiments, the number, shape, formation location, and the like of the notch portions are not limited to the above embodiment as long as solder or the like can be supplied to the inside of the connector terminal. Moreover, it is not necessary to form a notch part.

上記実施形態では、コネクタ端子は、平板状に形成され、幅方向の長さが厚み方向の長さよりも相対的に大きい。他の実施形態では、コネクタ端子の形状は、平板状に限らず、断面視正方形状や円形等、厚み方向の長さと幅方向の長さとが等しい形状等、どのような形状であってもよい。なお、コネクタ端子の形状に応じ、突出部と挿入部とは、長辺方向にずらした方が、短辺方向にずらすよりも確認可能な領域が多くなるので、望ましい。長辺方向、短辺方向が特にない端子形状であれば、突出部と挿入部とは、どの方向にずらしてもよい。   In the said embodiment, a connector terminal is formed in flat form, and the length of the width direction is relatively larger than the length of the thickness direction. In other embodiments, the shape of the connector terminal is not limited to a flat plate shape, and may be any shape such as a square shape or a circular shape in cross-section, such as a shape in which the length in the thickness direction is equal to the length in the width direction. . Depending on the shape of the connector terminal, it is desirable that the protruding portion and the insertion portion are shifted in the long side direction because more regions can be confirmed than in the short side direction. As long as the terminal shape does not have the long side direction and the short side direction, the protruding portion and the insertion portion may be shifted in any direction.

上記実施形態では、隣り合う２つのコネクタ端子は、線対称に形成され、挿入部は、互いに近接する方向、または、互いに離間する方向に、中間部から突出して形成される。他の実施形態では、隣り合う２つのコネクタ端子が線対称に形成されていなくてもよい。また、同一形状の複数のコネクタ端子が、同じ向きで横並びに配置されていてもよい。すなわち、中間部間の距離と挿入部間の距離とが等しくてもよい。また、複数のコネクタ端子の形状は、異なっていてもよい。   In the above embodiment, the two adjacent connector terminals are formed in line symmetry, and the insertion portion is formed so as to protrude from the intermediate portion in a direction close to each other or in a direction away from each other.
